Ok i'm worried I've just started using my 20D and i've noticed that every time I take an image I get a strange mark on the right hand side of the image. It isn't crap on the lens as I've tried my 2 other lenses and they all give the same result. It isn't crap on my LCD as I've uploaded the images to my PC and the mark is still there. I'm wondering if it is a body fault in which case i'm gonna need to send it back to where i got it from asap. The photos below show the mark i'm talking about.

That's obviously a new camera so personally I'd be very reluctant to attempt sensor cleaning at this point.
My suggestion is to send it back on warranty, that's assuming you can bear to part with your new toy so soon!

I developed this "problem" with my 10D the second day I had it. Simply went to the drug store, bought a "Ear Blower" thingy for $2.50 and gently blew off the sensor. Been great ever since. It's worth a shot anyway and it's cheap just DO NOT TOUCH THE SENSOR!!!! That is seriously bad Ju-Ju

That's an option but sensor dust has got to be dealt with on a semi-regular basis with a DSLR, it's part of the package....might as well start now.

Personally I'd try to do it myself with a blower, only if it looks to be more stubborn and won't shift would I take it back to the shop.

You're probably right but so far it's not happened to my 10D yet.
I believe it's because I'm paranoid when changing lenses and keep everything covered and capped as long as possible and make lens changes quickly.
I have acquired a cleaner kit but so far it's only been used on the lenses.
